Abstract

The invention provides a coal-based gas dreg light-weight micro-pore concrete composite sheet material and a preparation method thereof. The composite sheet material is formed by compounding a decorative mortar surface layer and a light-weight micro-pore concrete heat-preservation layer; coal-based gas dreg discharged in an industrialized process is taken as light-weight aggregate, has good heat-preservation performance, light weight, heat insulation performance and high specific strength, is wholly made from inorganic materials, and has the characteristics of nonflammable property and good durability; the defects that a heat preservation system of current frequently-used sheet materials, such as polystyrene plates, is flammable, the outer decoration easily forms swelling and falls and the service life is extremely lower than that of a building are overcome; and more importantly, industrial waste dreg is recycled so that the cost of the sheet material is extremely reduced, dual benefits of eliminating environment pollution and saving building energy are realized, non-renewable natural building material resources are protected, and the sheet material has real and long-lasting meanings on national economy and livelihood of people.

Description

technical field [0001] The invention belongs to the field of building materials, and specifically designs an environmentally friendly and energy-saving coal-made gas slag lightweight microporous concrete composite plate and a matching preparation method. Background technique [0002] Statistics show that about 2 million tons of coal-to-gas ash (referred to as coal-to-gas slag) are discharged in my country every year. Since they cannot be effectively utilized, such a large-scale waste has a serious negative impact on the environment. After my country formulated the coal-to-gas plan, coal was first made into gas, and gas was used as fuel to supply users. The implementation of this plan further increased the output of coal-to-gas slag, and the resulting environmental problems became more prominent. On the other hand, the mass production of traditional boards such as clay bricks requires a large amount of high-quality clay, which in turn leads to the destruction of large areas o...
